What Rb26 Parts Are Needed For 26/30 Engine Setup


Recommended Posts

Im investigating a new setup for my car and am looking for a list of the parts i need from a rb26 donar engine? i dont know if its worth buying an entire engine and selling the bottom end or buying a complete head and sourcing the harmonic etc elsewhere?

heres my idea of what i need so far..

head

cams

retainers

springs

valves

bucket and shims

cas

plenum/throttle bodies

do i need the oil cooler block that the oil filter goes onto or can i just run my sandwich plate straight from the block?

harmonic balancer, does it need to be a 26 one?

injectors im gonna upgrade so dont need them

tensioners can i use the rb30 ones or do i need 26 ones or are they both the same?

i have a gtr water and oil pump in my parts stash so they are sorted

im going to run single turbo setup so i dont need any turbo side stuff at all.

anything im missing from the list?

looks like it might be worth just buying a head complete and sourcing the other bits if i dont need too many hard to find parts.

26 wiring loom

look for an R32 thats had the oil pump let go, and taken the bottom end with it. all too common so shouldnt be too hard to find, and should be relatively cheap, just throw the bottom end in the bin

the balancer has to match the accessories off the model of the car... going buy what car your putting your engine into, i bought an ATI balancer for a R34, because i plan on using the existing alternator and etc, hope that makes sense...

you need different pistons as well,l well i don't know if you definitely need... but we went with a new set from JE they have a CR 8.7:1

Im also pretty sure the GTR springs are alright i think its mainly the 25 heads where its a big on changing the springs

if you can find an rb26 head that would be sweet but i think you will find allot of people don't want to separate, but one will pop up sooner or later if your patient i guess.

hope that helps you or at least steers you in the right direction i can PM you a list of everything Ive purchased, although mine is for teh rb25 head.... good luck

    • You all are absolute legends! Thank you for helping me put this into context with your comparisons!
    • There's probably an underlying issue with the A/C system too. I recently fixed mine, now it's fully control by the Haltech and car's factory HVAC controller  Have a squiz here:    
    • And by the way, I've also checked the ECU diagnostic numerous times and got a bad O2 sensor code and initially an Ignition Primary code, which is why I replaced the O2 sensor and all the ignition components (coil packa, plug and loom). No codes have been coming up lately despite the ongoing issue.
    • Hey pber13, unfortunately still no luck. At this point the following has been done with little or no success: - Spark plugs replaced, gapped to 0.8mm - Splitfire coilpacks installed to replace originals - Replaced Ignition Coil/Coilpack harness with a new genuine nissan one - New fuel filter - Replaced AFM/MAF sensor - Injectors have been thoroughly cleaned with an online flush (without removing) - Upper engine and inlet decarbed - blew tons of black smoke out, cleared the carbon deposits from the top of the engine and exhaust.  - IACV removed and thoroughly cleaned with carburettor cleaner - O2 sensor replaced with new and genuine one -  Smoke test revealed no vacuum leaks - Healthy compression test of 160psi across all 6 cylinders Overall the car does run a lot smoother now, no backfires between gear shifts like it did originally... but the rough idle when warmed up is still there. It may not even be a misfire but simply a rough idle. Seems crazy to me that so many people have had this issue and seemingly no one has gotten to the bottom of it, or at least never bothered to post if they did! Hope you have more luck than I did pber13, I'm at a point now where I'm just going to try to ignore it unless it gets worse. Would love to fix it but I've genuinely run out of ideas of what it could be.
    • I got the full frenchys kit too. Really awesome kit. Easy to install my only complaint was the hardlines I think could be routed differently (I modified mine) but I realise the kit needs to suit multiple applications. This was the hard lines before I modified them. They were touching the wastegate pipe. I ended up reducing the distance between firewall and first bend. The made it so they tucked along the frame rail.
